[Air-l] learning in internet-based networks

Dear all, On behalf of a colleague of mine, I would like to post the following request for information: I've been asked to help two regional internet-based networks that operate throughout Latin America to assess the extent to which they are stimulating learning in rural development. What frameworks exist that can help networks undertake the monitoring and evaluate of their impact - in terms of learning - among the network members? many thanks, Joyce Lamerichs Communication and Information Studies Wageningen University and Research Centre
